Raise cheer to welcome English victor (7)
I believe the answer is:
elevate
'raise' is the definition.
(I know that raise can be written as elevate)
'cheer to welcome english victor' is the wordplay.
'cheer' becomes 'elate' (to elate is to cheer or make happy).
'to welcome' is an insertion indicator (inserted letters are welcomed in).
'english' becomes 'E' (abbreviation).
'victor' becomes 'V' (phonetic alphabet: alpha, bravo, charlie etc.).
'e'+'v'='ev'
'elate' placed around 'ev' is 'ELEVATE'.
(Other definitions for elevate that I've seen before include "Raise or lift" , "Lift to higher place or position" , "Uplift" , "Raise, exalt (in rank)" , "Raise to a higher position" .)
